BW NW HW HWT PW 1.5m / 3m High-Quality Alloy DCDMA Standard Casing Tube
Description:
The casing tube joins to tapered joint with modified buttress
thread. It is made from high-quality alloy mainly used in
geotechnical and hammering applications.
The casing tube is cooperated with the casing shoes to stabilize
the borehole. It can well-adjusted to the broken formation stones.
Features:
Before drilling, drill rods should be in operation under the
minimum recommended make-up torque to pressure the box and pin. The
drilling operation torque should be lighter than make-up torque.
Specifications:
The casing tubes include NW tubes, HW tubes, and HWT casing tubes.
W
This casing tube is used for specific applications or when it's in
the drilling hole. The W casing borrows from DCDMA C80 tubing and
the DCDMA W thread form. With a straight thread, this general
casing is suitable to various drilling fields where thread casing
is required to be left in the ground.
Tubing
Parallel wall tubing is cooperated with Q.E wireline in-hole tools,
and standard DCDMA W sizes are compatible with other W casing
Thread design
Double-butt joint makes driving and jarring more powerful.
WT
This casing is an upgrade version of the standard W casing in speed and performance. Even in abrasive applications. This thread works well under difficult drilling conditions and is designed for repeated application. The WT casing used DCDMA C80 tubing and the tapered HD thread functions well.
Thread design
1.It is combined with HD rod threads.
2.Tapered joint and sparse thread greatly increase efficiency,
lightens friction and reduces labor costs.
3.Double-butt tapered joint and heavy duty buttress thread form
work with more strength.
4.Tapered thread reinforces the joint and effectively reduces
wearing.
5.40% Load efficiency means greater withdraw force in coarse
applications.
6.Threads are easier to clean to be put into use again.
